Using Le-Chatelier's principle, predict the effect of
(i) decreasing the temperature
(ii)increasing the temperature on each of the following :
(a)`N_2(g) + 3H_2(g) hArr 2NH_3(g) " " DeltaH`=-ve
(b) `N_2(g) +O_2(g) hArr 2NO(g) " " DeltaH`=+ve

For the reaction N_(2)(g) + 3H_(2)(g) hArr 2NH_(3)(g), DeltaH=?

Using Le-Chatelier's principle, predict which conditions of termperature and pressure would give high yield of products in the following reactions: (i) CO_2(g) + H_2(g) hArr H_2O(g) + CO(g) " " DeltaH =+41 kJ (ii) 2SO_2(g) + O_2(g) hArr 2SO_3(g) " " DeltaH =-198 kJ (iii) N_2(g)+O_2(g) hArr 2NO(g) " " DeltaH =175 kJ

Which of the following factors favour the reaction: N_2(g) + 3H_2(g) hArr 2NH_3(g) DeltaH =-93.6 kJ

Explain the effect temperature on the endothermic reaction: N_2(g) +O_2(g) hArr 2NO(g)
